“All I could see was two sets of red eyes below me,” said Dave Gatty, an Australian farmer who spent seven days up a tree in remote bush land to escape crocodiles. Gatty, 52, said he was forced to take such drastic action after he accidentally went into a crocodile-infested area of Queensland. He only had two meat sandwiches to keep him going, as crocodiles moved beneath his tree each night until his rescue. Gatty said he decided it was safer to hold out for a rescue team than try to make a run for it. His problems began after he fell off his horse while out in the northern Australia outback. Dazed and bleeding, he climbed back on his horse and hoped it would lead him home. It was only when he regained his senses he realized that he had been taken into crocodile-infested area. “I had to get off the horse and I fell straight into a crocodile nest,” he told reporters. 

“That frightened me. I couldn’t go back, it was too far and too dangerous, so I headed to the nearest high ground and stayed there, hoping someone would come and find me before the crocs did.”

Gatty explained how each night two crocodiles would sit at the bottom of the tree staring at him. Although Gatty’s two sandwiches ran out after three days, he was able to get running water during the day and knew rescuers were looking for him as he could see helicopters in the air above his tree.

“If I hadn’t seen the crocs circling me, and if I hadn’t fallen into the croc nest, I would have made a push for it. But I knew the safest thing was for me to sit and wait,” he said. A chocolate bar, given to him by rescuers after being moved to safety by using a winch(卷扬机), “was like a gourmet (delicious)meal,” he said.
